ZEUS实验卡尔曼滤波拟合的改进

Improvement of the Kalman Filter Fit of the ZEUS experiment

V. Roberfroid

摘要:

在位于汉堡DESY的HERA对撞机上的ZEUS探测器中心,2000/2001年安装了一个微型顶点探测器。该子探测器位于光束线附近,用于精确测量相互作用点(顶点)附近的轨迹。一个名为KFFIT的软件包被指定使用卡尔曼滤波器执行微顶点检测器命中的跟踪拟合。本文报告了该软件包中所做的所有改进。在对算法进行简要描述之后,将介绍KFFIT的最新版本(2006年12月发布的v10)与初始版本(2005年12月发布的v1(=v2005a.1))的比较。

英文摘要:

At the center of the ZEUS detector situated on the collider HERA at DESY in Hamburg, a Micro Vertex Detector has been installed in 2000/01. Situated close to the beam line, this subdetector is designed to measure precisely the tracks near the interaction point (the vertex). A package called KFFIT is designated to perform the track fit of the Micro Vertex Detector hits using a Kalman Filter. This paper is a report of all improvements done in this package. After a brief description of the algorithm, the improvements of KFFIT will be presented comparing the last version (v10 released in December 2006) to the initial one (v1 released in December 2005 (=v2005a.1)).
